Add Dockerfiles to Containerize Frontend and Backend of the Project

[devanmolx]

This PR introduces Dockerfiles for both the frontend (Vite-based) and backend (Go-based) of the project, enabling containerization of the development environment. A .dockerignore file has also been added to optimize the Docker image size by excluding unnecessary files. Additionally, the documentation has been updated to reflect the new setup steps.

Fixes #54

Changes Introduced:

Frontend Dockerfile:

Added a Dockerfile to containerize the frontend, exposing port 5173 for local development with Vite.
Included necessary dependencies and environment setup to run the frontend within the container.

Backend Dockerfile:

Added a Dockerfile to containerize the backend, exposing port 1313 for the Go server.
Handled graceful shutdown of the backend to ensure proper termination when the container stops.

.dockerignore Files:

Added .dockerignore files to both frontend and backend to reduce Docker image size by ignoring files like node_modules, logs, and temporary files.
